Benefits of technology

The present invention proposes a method for transmitting data signals and reference signals on a sidelink subframe. The method involves boosting the transmit power of certain resource elements by a certain amount and transmitting the signals repeatedly in a specific pattern. This improves the reception of the signals and reduces interference between them. The invention also provides a wireless device for performing the sidelink subframe transmission. Overall, the technical effect of the invention is to enhance the efficiency and reliability of sidelink communication.

Problems solved by technology

As described above, since the V2X UE cannot use the first symbol OFDM / SC-FDMA symbol and the final symbol OFDM / SC-FDMA symbol of a subframe, performance restriction, that efficiency of frequency spectrum is limited.

Abstract

The disclosure of the present invention proposes a method for performing a transmission on a sidelink subframe. The method may comprise: performing the transmission on the sidelink subframe. The sidelink subframe may include a plurality of symbols in a time domain, each of which includes a plurality of resource elements (REs) in a frequency domain. The transmission may include transmitting at least one of a first data signal and a first reference signal (RS), which is repeated in one or more REs in a last symbol with a periodicity of NRPT_L, The one or more REs having the periodicity of NRPT_L in the last symbol may have a boosted transmit power for transmitting the at least one of the first data signal and the first RS.

Description

[0001]This application claims the benefit of priority of U.S. Provisional Application No. 62 / 379,227 filed on Aug. 24, 2016, which is incorporated by reference in its entirety herein.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to mobile communication.Related Art[0003]3rd generation partnership project (3GPP) long term evolution (LTE) evolved from a universal mobile telecommunications system (UMTS) is introduced as the 3GPP release 8. The 3GPP LTE uses orthogonal frequency division multiple access (OFDMA) in a downlink, and uses single carrier-frequency division multiple access (SC-FDMA) in an uplink. The 3GPP LTE employs multiple input multiple output (MIMO) having up to four antennas. In recent years, there is an ongoing discussion on 3GPP LTE-advanced (LTE-A) evolved from the 3GPP LTE.[0004]In LTE / LTE-A, a physical channel of LTE may be classified into a downlink channel, i.e., a PDSCH (Physical Downlink Shared Channel) and a PDCCH (Physica...
